Description: Series power supply dynamic load performance did not parallel the good, Because when the series lead regulator power load is low pass degree, B approximation for dynamic load from 0 to accelerate to 60mA, Parallel power constant current source has a large current to the regulator, in the CPI for dynamic load simply accelerate from 30mA to 90mA, both reflect the speed is definitely not the same. The entire circuit board trace layout are very strict and reasonable, the overall PCB

High quality phono preamplifier allows turntables with high quality magnetic cartridges to be connected directly to home theater receivers that lack a phono input. It is also great for connecting turntables to personal computers or laptops for transferring vinyl LP's digital media. Internal RIAA equalization circuit provides proper response curve for correct emphasis from LP's.Rugged metal housingIdeal for turntables with moving magnet (MM) cartridgesPower LED indicationRCA female L/R inputs
